- Other means to achieve the attaching of the cover to the housing are envisaged, such as, sliding the cover over the housing.
- the faceplate 10 In order to move the faceplate 10 to a different position along the bus bar the faceplate 10 must be removed (for example, snapped off using a standard flat blade screwdriver or similar tool) and the back plate 11 unscrewed and removed from the housing 2 .
- the covers 30 then can be removed as described above referring to FIG. 4B and the back plate relocated to a new desired location.
- the back plate is then resecured to the housing 2 using screws 27 and the replacement covers cut to appropriate lengths are reinstalled to cover the exposed bus bar system and housing. Finally the faceplate 10 is reinstalled (snapped) onto the relocated back plate 11 .
- a number of back plates can permanently reside at appropriate locations along the bus bar therefore faceplates can be installed over the back plates at a number of points along the bus bar.
- FIGS. 8 and 9 show an alternative form of the bus system of the present invention.

The bus bar system is preferably mounted within a housing that extends horizontally along the base of a wall or other desired location. The receptacle has at least one continuously live power socket and at least one switched power socket disposed on it. Each of the power sockets is capable of receiving an appliance plug. The receptacle is movable along the bus bar to a different location to allow for appliances, for example lamps or computers, to be located at many different points along the wall.
- In other forms the distribution circuit may be a set of wires extending along housing and a receptacle including terminals that contact these wires. Furthermore, in yet other forms of the distribution circuit, a stand-along unit that is fixed in place may be provided.
- The preferred form of the electrical outlet apparatus of the present invention is shown in
FIG. 1 . Abus bar housing 2 is mounted on and extends along the base of a wall or at any other desired location on the wall. Thehousing 2 has arecess 3 extending within the entire length of thehousing 2. Arranged within therecess 3 are a number ofbus bars ground strips recess 3. Abus bar insulator 7 enclosesbus bars bus bar insulator 7 also provides channels to mount or locate theground bus bars upper contact strip 4 is a continuously powered (“live”) bus bar, thecentre contact strip 5 is a neutral bus bar, and thelower contact strip 6 is a switched bus (one that can be made live by the operation of a switch). Disposed above and below theneutral bus bar 5 are ground buses orstrips - Fitted to the
housing 2 and over the bus bar is a receptacle. The receptacle is made up of afaceplate 10 and backplate 11. Theback plate 11 is affixed to thehousing 2, and afaceplate 10 is fitted over theback plate 11. - Referring to
FIG. 6 ,hollow protrusions 26 in the shapes of the electric appliance plug pins protrude from the base of theback plate 11. When thefaceplate 10 is attached to theback plate 11, theprotrusions 26 fit into complimentary shapedapertures faceplate 10, but do not extend out from the faceplate surface. When thefaceplate 10 and backplate 11 are affixed to one another theapertures protrusions 26 form channels through thefaceplate 10 and backplate 11. Sets of these channels form at least one socket that is capable of accommodating at least one standard two or three-pinelectric appliance plug - Reference is now made to
FIG. 2 where, in particular, thebus bar system 25 is shown in detail. As mentioned above the bus bar system comprises two live buses, a neutral bus and two ground buses. The upperlive bus 4 is connected through a current limitingdevice 18 to standard wiring that extends to a termination or fuse box within a building, where the termination or fuse box is connected to an AC power source. The voltage of thelive bus 4 in some forms will be 230 Volts, but in others, such as when in use in a United States (US) power system it may be 120 Volts or any other appropriate voltage. The current limitingdevice 18 may be a circuit breaker, surge protector, fuse, ground fault circuit interrupter or any other appropriate device. The centre bus (lying between the two live buses) is theneutral bus 5. The neutral bus is also connected to standard wiring and to the termination or fuse box of the building (the termination or fuse box ultimately being connected to an electrical power distribution system). The lower live bus is a switchedbus 6 and is connected through a current limitingdevice 18 to wiring and then to one side of aswitch 17. Theswitch 17 is a standard switch or dimmer switch that is disposed in a building wall in a known manner. The other side of theswitch 17 is connected via standard wiring to the “live” terminal in the termination or fuse box. Finally, theground buses - Referring now to
FIGS. 3 and 10 , each of the bus bars 4, 5, and 6 is configured at intervals with receiving means. The receiving means areslots 14, which are integrally formed in each bus bar. Eachslot 14 is of a shape to receive a pin of a plug connected to a load or electrical appliance. Theslots 14 are shaped to form a tight connection between the bus bar and the pin of the plug. Theslots 14 are spaced incrementally along the length of each of the buses in order to allow for incremental relocation of theback plate 11 andfaceplate 10 along the bus bar system. Theslots 14 in the bus bars are preferably formed integrally in the bus bar by the incremental punching of the slots in the bus bar, but the slots may be formed by other appropriate ways. In the preferred form, eachslot 14 is formed when acentral section 48 of the bus bar is pushed downwards out of the plane of the bus bar, thereby forming a trough, and theside sections front plate 10 and back plate 11) and the pins from the plug extend through the receptacle into theslots 14 on the bus bar, for each slot and respective pin, thecentral section 48 lies below the pin and theside sections - In some forms of the present invention, a plug may be utilized that has three pins. A standard
electrical plug 15 is shown inFIG. 1 . In most forms such a plug has three pins, but in some forms may only have two pins. The first twopins plug 15 along parallel axes. Thethird pin 20 can be circular in shape, or may be of similar shape to the first two pins, but usually thethird pin 20 extends from the plug along an axis parallel but between the first twopins - Referring to the form of the three pin US type plug as shown in
FIG. 1 , in use, when the plugs are inserted in a socket formed in the receptacle, thefirst pin 19 is connected theneutral bus 5 andsecond pin 21 may either be connected to thelive bus bar 4 or switchedbus bar 6. Thethird pin 20 is connected to one of theground bus bars ground slot 22 inFIG. 3 . Incrementally spacedground slots 22 are formed in the ground bus bars. Theground slots 22 are similar to theslots 14 in the other bus bars, but in this form of the present theground slots 22 are shaped to receive thethird pin 20 of a standard US type plug. In other forms of the present invention theground slots 22 and theslots 14 can be identical. - Referring again to
FIG. 6 , theprotrusions 26 in theback plate 11 andapertures faceplate 10 form at least two sockets, one being a switched socket and the other a live socket. However, more than two sockets can be formed on thefaceplate 10, for example, inFIG. 1 , the faceplate has four sockets disposed within it, although in this form only two plugs are able to be received at one time within the sockets. -
FIG. 10 shows the bus bars 4, 5, 6, 8, 9 and twoplugs Plug 15 is in a position within the bus bars which cause the appliance attached to the plug to be “switched”. When a user operates the switch 17 (as shown schematically inFIG. 2 ) the appliance can be switched on or off. When a plug is inserted in the “switched socket” thefirst pin 19 resides within aslot 14 in theneutral bus 5. The second pin 21 (not shown inFIG. 10 , but being disposed below pin 19) resides within an aperture in the switchedbus 6. Theground pin 20 resides within theslot 22 in thelower ground bus 9.Plug 16 is in a position within the bus bars which cause the appliance attached to the plug to be continuously powered or live. When a plug is inserted in the “live socket” the first (upper)pin 23 resides within an aperture in thelive bus 4. The second (lower)pin 24 resides within aslot 14 in theneutral bus 5 and the ground pin (not shown in this view) resides within aslot 22 in theupper ground bus 8. - The construction of the circuit of the present invention will now be described with reference to FIGS. 4 to 6. As already discussed, the bus bar system 25 (consisting of the
bus bar insulator 7 andbus bars housing 2 where the housing is located on a wall within a building.FIG. 5 shows the end view of thebus bar insulator 7. The bus bar insulator has threehollow channels 43 to enclose the live, neutral, and switched buses. A continuousopen slot 44 is incorporated at one side of these channels to allow the electric plug pins to extend through the apertures in the bus bars.FIG. 5A is an isometric view of thebus bar 7 and shows the incrementally spacedopenings 45 for the ground bus slots 22 (as described earlier with reference toFIG. 3 ). As shown inFIG. 6 , theback plate 11 is attached to the upper 28 and lower 29 faces of thehousing 2 by appropriate means. In the preferred form of the invention, theback plate 11 is indexed laterally by a boss (not shown) on the back of theback plate 11. This boss protrudes through incrementally spaced holes 46 (FIG. 3 ) in theground buses FIG. 5A ). Theback plate 11 is then screwed to thehousing 2 using screws 27.FIG. 5B shows the completebus bar system 25 with all buses installed in the bus bar insulator. The remainder of the bus bar and housing that is not covered by theback plate 11 is then covered by a cover 30 (FIGS. 6, 7 ) formed from a plastics type material and cut to the appropriate length. - In
FIG. 6 thefaceplate 10 is illustrated as having a number ofnotches 32 that lock withcomplementary protrusions 31 formed in the back plate edges. When the faceplate is snapped over the back plate, theapertures faceplate 10 are aligned with thecomplimentary protrusions 26 of the back plate, so that when theplugs 15, 16 (seeFIG. 1 ) are inserted into these sockets, the pins extend through thefaceplate 10, backplate 11,open slots 44 ofbus bar insulator 7, and then into the slots within the bus bars. -
FIGS. 4, 4A and 4B show side views of the circuit.FIG. 4A shows aprotrusion 51 at the edges of thehousing 2 locking with a correspondingprotrusion 52 incover 30.FIG. 4B illustrates the installation and removal of thecover 30, which is achieved by squeezing and bending thecover 30 in order for theprotrusion 52 on thecover 30 to fit into theprotrusions 51 and into the housing, to cover the exposed parts of the bus bar system. Other means to achieve the attaching of the cover to the housing are envisaged, such as, sliding the cover over the housing. - When the receptacle (
faceplate 10 and back plate 11) is completely installed as shown inFIGS. 7 and 7 A, the gaps between thecover 30 and backplate 11 are covered by the ends offaceplate 10 thus providing for a safe and secure connection of the receptacle to the housing. - In order to move the
faceplate 10 to a different position along the bus bar thefaceplate 10 must be removed (for example, snapped off using a standard flat blade screwdriver or similar tool) and theback plate 11 unscrewed and removed from thehousing 2. Thecovers 30 then can be removed as described above referring toFIG. 4B and the back plate relocated to a new desired location. The back plate is then resecured to thehousing 2 usingscrews 27 and the replacement covers cut to appropriate lengths are reinstalled to cover the exposed bus bar system and housing. Finally thefaceplate 10 is reinstalled (snapped) onto the relocated backplate 11. - A number of back plates can permanently reside at appropriate locations along the bus bar therefore faceplates can be installed over the back plates at a number of points along the bus bar.
-
FIGS. 8 and 9 show an alternative form of the bus system of the present invention. This form is more appropriate for a power system within New Zealand. In this form thebus system 35 is arranged in a different manner so that the bus bars andsockets upper bus bar 39 is the live bus bar and thelower bus bar 40 is the switched bus bar. Thecentre bus bar 36 is the neutral bus bar and the bus bars above and below theneutral bus bar 36 are theground buses 37, 38. In this form the slots in the live, switched and neutral bus bars 41 are of the same configuration as theslots 42 in the ground bus bar, in order to accommodate the pins of a New Zealand style plug. This form of the electrical outlet of the present invention is constructed and operates in the same manner as is described above. - In other forms of the present invention a channel may be provided along the bottom of the
housing 2 for the passage of telecommunications lines, such as a phone line or Internet line (CAT 5). The telecommunications line would preferably terminate at a socket formed in the faceplate, the socket would be of the type in which electronic equipment such as computers or telephones could be plugged into. - As already mentioned, the housing and bus bars extend along the length of walls within a building. In order to facilitate the extension of the bus bars around corners of the walls a number of clips are provided within the bus bar system that accept the rectangular end of the bus bars on one side and at the other side are attached to standard bendable wiring that extends around a corner and connects back into a second clip. The other side of the second clip is connected to a further rectangular end of the bus bar and the length of the bus bar extends along the length of a second wall. An alternate method of extending the continuity of the bus bars around corners is to utilize standard solder joints with wires.
- As the faceplate is positionable at any number of different locations along the bus bar, the need for extension cords is minimized or eliminated. This provides a less cluttered room appearance and reduces the likelihood of tripping over or damaging extension cords. Furthermore, fire and other safety hazards are minimized. In comparison to a conventional electrical outlet embedded in a wall, it is very easy to change the location of the receptacle of the present invention and this can be accomplished with a minimum number of standard tools very quickly (time from start to finish should average less than 10 minutes). Also, the addition of new receptacles can be accomplished just as easily. Usually, changing the location of a conventional electrical outlet typically requires removing the drywall surrounding the outlet, removing the drywall surrounding the desired new location, securing the outlet to an internal beam or structure of the wall at the new location, extending the electrical wires (within the wall) to which the outlet is connected, and applying new drywall or filler at the old and new locations of the outlet.
- The faceplate and back plate, forming the receptacle, can be configured to receive any desired number of plugs for different electrical appliances (or electrical plugs). With redesign for different plug types, the basic concept of this apparatus can be adopted to any electrical system worldwide. Furthermore, the receptacle can be configured to receive different types of connectors, such as connectors for telephone wires, coaxial wires for cable television and/or cable modems, OSL wires, fiber optics, and the like (this would allow these connections to be relocated just as easily as the electric power outlets).
- The receptacle of the present invention also provides a user with both a switched power socket and a continuously live power socket thus offering more versatility in placement of appliances and or lamps.
- Referring now to FIGS. 11 to 15, an alternative embodiment of the circuit of the present invention will be described where a plurality of
wires terminals elongated recess 64 is provided that houses the plurality ofwires FIG. 11 , the extruded housing is made from a plastics material and houses four wires, a switchedwire 60, one that can be made live by the operation of a switch,neutral wire 61, continuously (“live”)wire 62 andground wire 63. Each of these wires is connected to a termination or fuse box of a building, whether by way of standard wiring or directly to the box. A receptacle comprising afaceplate 70 and backplate 69 and a plurality ofterminals FIG. 6 . - Located behind the
back plate 69 are a plurality ofterminals housing 64. Therefore, there is aground contact terminal 65, switchedcontact terminal 66,neutral contact terminal 67 and continuously powered (“live')contact terminal 68. Each of these terminals has receiving means orslots plug electrical plug 73 connected to an electrical appliance. As an example, the slots in the switched 66, neutral 67 and live 68 terminals preferably receive one of the twonarrow pins 77, 78 (similar to thosepins FIG. 1 ) of theplug 73. Theground terminal 65 has aslot 75 that is capable of receiving thelarger pin 79 of theplug 73. Each of the terminals is fixed to theback plate 69 and is arranged such that when the receptacle is fitted to thehousing 64 part of each terminal abuts the corresponding wire. - The
faceplate 70 has apertures 72 and theback plate 69 hascomplimentary protrusions 76 that form a channel through the receptacle, such that at least a switched and a continuously powered socket are provided on the receptacle. As with the embodiment described above, the switched socket can be operated by a switch and the other is continuously live. Anelectrical appliance plug 73 haspins terminals plug 73 may be plugged into one of the two sockets on the receptacle and each of the pins connect with a particular terminal, much in the same manner as discussed above in relation toFIG. 10 , to form either a switched connection or continuously powered connection. - Referring now to
FIGS. 12 and 13 , each of theterminals apertures elongated housing 64 and the end of the extensions of the contact terminals abuts the wires housed within theapertures housing 64. A firm connection is made due to the spring tension in each of the waved extensions causing the ends of the extensions to push down on each wire, as shown inFIG. 13 . - Referring now to
FIGS. 14 and 15 , theground contact terminal 65 has anextension 83 that extends below the main body of the terminal 65 to contact theground wire 63. - The receptacle and wiring system of this embodiment of the circuit of the present invention allows for the receptacle to be moved along the
recess 64 and placed at an infinite number of positions along therecess 64, thus giving the user flexibility in the choice of locations of the receptacle and subsequently sockets. This form of the present invention provides advantages over the form described above in relation toFIG. 1 . The bus bar system ofFIG. 1 only allows for set positioning of the receptacle over the slots formed in the bus bars. In this alternate embodiment the receptacle can be slid along therecess 64 and thecontact terminals 65 to 68 will merely slide along thewires 60 to 63. Also the problem of continuing the electrical continuity around corners using the bus bar system is eliminated since thewires 60 to 63 can simply be bent around corners. - A stand-alone circuit is shown in
FIGS. 16 and 17 . This circuit would be suitable to replace existing stand-alone power sockets. Here areceptacle 108 has a face plate (not shown) andback plate 109.Terminals back plate 109. The terminals haveslots screws FIG. 11 and provide for both a switched power socket and a continuously live electrical power socket.
